to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...

The cowpea bruchid, Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae: Bruchini), is a worldwide pest of stored cowpea grain [ Vigna unguiculata (L.) Walp. (Leguminosae)], causing tens of millions of dollars’ worth of damage annually. One method of managing this pest involves planting cultivars whose seeds are resistant to bruchids. Despite extensive research, we still do not know the me...

Various seed treatments were evaluated for their effect on early-season corn pests. Imidacloprid at low and high rates (Gaucho and Prescribe , respectively) and thiamethoxam (Cruiser ) at low and high rates were effective in reducing populations and exhibited systemic insecticidal activity against chinch bugs, flea beetle, wireworm, white grub, and southern corn leaf beetle. Another systemic ne...

Cowpea contains phenolic compounds that are beneficial to huma...

Seed blends containing various ratios of transgenic Bt maize (Zea mays L.) expressing the mCry3A+eCry3.1Ab proteins and non-Bt maize (near-isoline maize) were deployed alone and in combination with a soil applied pyrethroid insecticide (Force CS) to evaluate the emergence of the western corn rootworm, Diabrotica virgifera virgifera LeConte, in a total of nine field environments across the Midwe...

Cowpea seed beetle, Callosobruchus maculatus (F.) (Coleoptera: Bruchidae), is considered an important bruchid pest in cowpea storages. The used pesticides against this have caused the occurrence of resistant populations and direct toxicity to users. objective study was evaluate mortality effects six entomopathogenic fungi isolates obtained from ARSEF (USA) collection [Paecilomyces farinosus (25...

Viral attacks on natural populations of herbaceous forage legumes might have adverse effect on seed and herbage production, hence this study was carried out to investigate the type and incidence of viruses occurring on these plants in Nigeria. Protein A-sandwich (PAS) and antigen-coated plate (ACP) enzyme-linked immunosorbent assays (ELISA) were used to detect ten legume viruses from 100 leaf s...

Livestock is an important sector of agriculture, but good quality forage is one of the major limiting factors for the growth of this industry. Studies were conducted to compare the forage quality of maize and legumes sown in pure stand and in mixture in randomized complete blocks during 2005 and 2006 at the University of Agriculture Faisalabad, Pakistan. Maize (Zea mays L.) and three legumes [c...

Cowpea crop, through combining a range of essential minerals with high quality proteins, plays an important role in providing nutritional security to human population living in semi-arid regions. Studies on genetics of biofortification with essential minerals are still quite scarce, and the major objective of the present study was to provide genetic information on development of cowpea cultivar...

The objective of the study was to evaluate chemical composition, in vitro dry matter digestibility (IVDMD), and growth performance of weanling Boer-goats supplemented with cowpea seed hulls (CSH) and commercial concentrate / feed (CF) with natural pasture as basal diet. Weanling Boer-goats (n=36) were assigned to 3 treatments comprising of 4 animals each (2 bucklings and 2 females) replicated t...
